It is found in southern Canada and the northern United States, from Labrador to Vancouver Island, south in the Appalachians, Ozarks and Rocky Mountains to North Carolina and Mississippi and south in the west to Arizona.
The wingspan is 30–39 mm. Adults are on wing from May to August. There are two generations per year. The larvae feed on the leaves of Rubus species (including black raspberry and purple-flowering raspberry). Wikipedia →

Rare
Under 5% of wildlife watchers report a Lettered Habrosyne Moth sighting in Vancouver on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 258th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lettered Habrosyne Moth in Vancouver on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Lettered Habrosyne Moth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Vancouver, in our data
Vancouver is the only city on Wallace's Line with enough records to rate Lettered Habrosyne Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Lettered Habrosyne Moth is recorded against all the insects logged in Vancouver (17 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
